Ask Claude or ChatGPT about Substack and it guesses from training data that is months old, or runs a web search and summarizes blog posts. No current numbers, no history, no dates.
It reads Substack directly: top newsletters, newsletters by category. Every answer has the real numbers and the date they are from.
Click your app. It opens with TrendsConnector already filled in. You sign in once with a free TrendsConnector account; there is no API key to copy.
| App | After you click |
|---|---|
| Claude | The connector name and URL are prefilled. Confirm, sign in to TrendsConnector, approve access. |
| ChatGPT | Turn on Developer mode under Settings → Security and login. Name it TrendsConnector, URL https://trendsconnector.com/mcp, choose OAuth, sign in. |
| Cursor | Approve the install. Sign in to TrendsConnector when Cursor asks. |
| VS Code | Approve the install. Open Chat in Agent mode and enable the TrendsConnector tools. |
One connector covers every source, so Substack works the moment you add it. Other apps (Grok, Muse, Perplexity, Gemini, Claude Code and more): setup for every app.
